Convert the following percent to a decimal: 56 percent.

mihalych1998 [28]

Answer:

0.56

Step-by-step explanation:

Percent means 'per 100'. So 56% means 56 per 100 or simply 56/100. If you divide 56 by 100, you'll get 0.56.

56/100 = 0.56

3. A jet traveled at an average speed of 681 kilometers an hour. At that rate, how far did the jet go in 7 1/4 hours?

Click the photo )) give three numbers between -7 and 9 that satisfy the given condition.

Veronika [31]

13 3/39 is too big, it's greater than 9, so that one is out.
16 is an integer, so that one is out too. 99/6 = 16.5, which is greater than 9, so it can't be right

So the answer is the other 3

Is shipping box is a shape of a cube. Each side measures 3c^6d^2 inches. Express the volume of a cube has a monomial.

liubo4ka [24]

Length of each side of cube is = $3c^6d^2$

SO the volume of cube = $(Side)^3$
= $(3c^6d^2)^3$
= $27 * (c^6)^3(d^2)^3$
= $27c^{18}d^6$

SO the volume of cube is $27c^{18}d^6$
